Hola mate,

Here is your answer.. :)

RIBS : The ribs help in the expansion and contraction of the thoracic cavity (though that is primarily the function of the diaphragm) and also protect the lungs and heart.

DIAPHRAGM : The diaphragm decrease the air pressure within the lungs so as to let air from the outside flow into our lungs.

Explanation:

    RIBS    

When the diaphragm expands or contracts, the thoracic (chest) cavity expands or contracts, alternately pulling in air (inhalation) or expelling it (exhalation).

The ribs, which are flexible, along with the intercostal muscles, help in this process. Since expansion of the lungs is greater in the lower lobes, the floating ribs enable that process.

The ribs also form a protective cage around the heart and the lungs, protecting them from physical damage from outside.

    DIAPHRAGM    

The diaphragm is a skeletal (voluntary muscle) that contracts when we breathe in. Its purpose is to decrease the air pressure within the lungs so as to let air from the outside flow into our lungs. It's essentially creating a vacuum so air can come in and fill the void created by the "pulling" on our lungs. This new air coming in lets us exchange oxygen out of the air, for use by all our body's cells.

Answer 2

Ribs:-

in inspiration ribs move upward and outward in expiration ribs move outwards and downwards

Diaphragm:-

in inspiration diaphragm contracts and flattens downward and in expiration diaphragm relaxes and move upwards to dome shape
